What should you do if a lithium battery device is on fire?

Using a fire extinguisher specifically designed for electrical fires is the appropriate response when dealing with a lithium battery device that is on fire. Lithium batteries can pose significant hazards during combustion, often resulting in an intense fire that can be further exacerbated by certain types of extinguishing materials.

Fire extinguishers labeled for electrical fires, such as those rated for Class C fires, are specifically designed to tackle the unique risks posed by electrical equipment and flammable materials. These extinguishers typically use non-conductive agents to safely suppress the fire without conducting electricity, thus minimizing the risk of personal injury or further damage.

While it may be tempting to use water or other common items to extinguish a fire, they can react poorly with lithium battery fires. Water, for instance, can react violently with the flaming materials and potentially spread the fire. Similarly, smothering the fire with a blanket may not effectively suffocate the fire and could endanger the person attempting to intervene. Removing the device from a heat source does not address the active fire and is insufficient as a firefighting strategy. Thus, employing the correct type of fire extinguisher is crucial for safe and effective fire management in this scenario.
